Cloud Electronics VA4120 4-Channel 120W 25/70/100V Power Amplifier

Cloud Electronics VA4120 4-Channel Power Amplifier

The VA4120 is a professional 4-channel power amplifier designed for commercial audio applications, delivering 120W per channel. Built for simplicity and reliability, it can drive either low-impedance loudspeakers (minimum 4Ω) or high-impedance 25/70/100V line distribution systems, making it highly flexible for a variety of installations. Each channel features preset gain controls and switchable high-pass filters to optimize performance and reduce transformer saturation at low frequencies.

For enhanced protection and longevity, the VA4120 incorporates per-channel limiters to prevent clipping, over-temperature shutdown, and DC output protection. All connections and controls are conveniently located on the rear panel, while the front panel features LED indicators for signal presence, excessive level, and amplifier protection activity. Forced-air cooling ensures stable operation even under heavy use.

Ideal for retail, hospitality, leisure, or industrial environments, the VA4120 combines efficient amplification with robust protection circuitry. Its compact 2U rackmount design and user-friendly setup make it a dependable choice for multi-zone audio systems that require reliable, high-quality sound across multiple channels.
